近墨者黑:上市公司违规行为的“同群效应”

近年来,上市公司违规行为群发,本文利用2000-2016年沪深A股上市公司违规事件样本,从“同群效应”的角度探究违规行为的群体特征和影响因素。研究发现,上市公司违规行为存在显著的地区同群效应(“近墨者黑”),同地区其他上市公司的违规行为显著增加了该地区公司发生违规行为的概率;且信息披露型违规的同群效应更加明显。机制研究表明,企业违规决策的地区同群效应主要源于交流式学习和观察式学习的两种模仿作用机制。异质性分析表明,同一地区内,相同产权性质公司间的同群效应更明显。进一步研究显示,十八大之后违规行为的发生概率显著降低,地区同群效应显著减弱。本文研究揭示了违规行为的地源性特征,也从抑制违规传染视角实证支持了近年来的系列整治活动。

博士毕业生就业选择研究:综述与展望

就业作为博士教育运行机制的终端,是对博士生培养质量的重要检验.已有博士毕业生就业选择研究主要围绕整体就业率、就业选择趋向、就业选择差异性等方面展开,达成了一些共识,为了解博士毕业生就业选择提供了有效途径.但相关研究在数据来源以及研究内容上普遍存在年限单一、院校单一或分析维度单一等问题,未来研究需采用多年限、多院校、多维度分析的方式对博士毕业生就业选择进行更加准确、深入、全面的呈现.     

TBL教学法在专科生化教学中的应用探讨

目的:探讨TBL教学法在专科生物化学理论教学的教学效果。方法:曲靖医学高等专科学校2012级临床专业的129名学生,随机分为TBL组和LBL组,课后进行问卷调查和考核。结果:大多数学生对TBL教学满意,TBL组考试成绩得分明显高于LBL组。结论:TBL应用于生物化学教学,效果优于LBL。TBL有助于培养学生自主学习和综合能力,促进学生团队协作,是进行生物化学理论教学的有效模式,值得推广。

The societal relevance of management accounting innovations: economic value added and institutional work in the fields of Chinese and Thai state-owned enterprises

This paper contributes to the ongoing debate about the relevance of management accounting. In doing so, we widen the definition of ‘relevance’ from the largely managerialist focus dominating this debate to examine how management accounting innovations get imbued with a broader range of societal interests and how actors representing vested interests go about entrenching and resisting such innovations. We explore these issues with reference to the institutionalisation of Economic Value Added (EVA?) as a governance mechanism for Chinese and Thai state-owned enterprises. Adopting a comparative, institutional field perspective, we theorise our observations through the conceptual lens of institutional work, or the human agency involved in creating, maintaining and disrupting institutions. We extend extant research on institutional work by exploring how the evolution of such work was conditioned by differences in field cohesiveness, defined in terms of how consistent and tightly coordinated key interests clustered around EVA? are. Our analysis also draws attention to how different types of institutional work support and detract from each other in the process of upholding such cohesiveness. We discuss the implications for future research on the societal relevance of management accounting innovations and institutional work.     

细点圆趾蟹的几种加工工艺研究

本文通过介绍细点圆趾蟹的两种加工工艺,研究了冷冻时间对细点圆趾蟹品质的影响,确定冷冻时间5 d以上对细点圆趾蟹黑变、鲜度和肉质都有着严重的影响,因此在加工时要选择冷冻时间低于5 d,新鲜无黑变的细点圆趾蟹。本研究为食品加工企业对下脚料细点圆趾蟹的深加工提供了参考价值。

"特朗普税改政策"的溢出效应及中国的应对策略

特朗普税改使美国成为税收洼地,各国为争夺国际资本竞相效仿降税,加剧了全球税收竞争,为世界经济复苏增加了更多的不确定性.因此,有必要通过构建利润转移视角的税收竞争模型,揭示特朗普税改对全球经济产生溢出效应的作用机制及赤字约束问题,并运用一般均衡模型(CGE)模拟特朗普税改对世界经济溢出效应的长短期影响.特朗普税改是以邻为壑的经济政策,但长期内对中国等世界主要经济体的负面影响不断减弱,并会对出口产生一定的正面影响.因此,我国应构建国际税务交互管理体制,强化企业税收激励的法制保障,完善税改冲击的应急运行机制.     

Does IFRS Adoption Increase the Accuracy of Chinese Analysts’ Forecasts?

This article investigates the impact of International Financial Reporting Standards (IFRS) adoption on the accuracy of Chinese analysts’ earnings forecasts. We find that after IFRS adoption, the accuracy of Chinese analysts’ forecasts decreases rather than increasing as they do in developed countries documented by the extant literature. Further investigation finds that this decrease is associated with a fair value measurement of financial assets held for trading. Our finding provides empirical evidence supporting the argument that the effectiveness of IFRS adoption could be negative in a developing country depending on its setting and fair value measurement brought about by IFRS could contribute to the negative effect in this setting.
